void SPI1_Init_Advanced(char mode, char fcy_div, char
clock_and_edge)
Returns Nothing.
Description
Configures and initializes SPI. SPI1_Init_Advanced or SPI1_Init needs to be
called before using other functions of SPI Library.
Parameters mode, fcy_div and clock_and_edge determine the work mode for
SPI, and can have the following values:
Note: Some SPI clock speeds are not supported by all AVR MCUs and these
are:
Fosc/2, Fosc/8, Fosc/32. Please consult appropriate datasheet.
